bypass meizu lock pin / pattern by update

i try to unlock meizu mx6 phone and i search tools to bypass the lock but nothing work

on youtube there is many video but not really works

you can unlock the lock code with cmd comments but the phone not recognize in the pc

you can update the phone to new version or to same version you right now but you need sd card but you dont have one

if your phone is turn on and you connected the phone to pc you can see the name of the phone under my computer but when you enter
to phone files there is nothing and if you copy or drag files to ph

its fail

so what you an do the way to bypass the transfer files to phone is
to enter to recovery like this image

now after you transfer the files to recovery folde you can updae the firmware to new version and from this screen

now choose both of the options and press and as you can see the phone start to updae without pc tools or sd card
